Fairbanks 5260 Series Unirail - Manual (Page 16)

6. Using a 3/.4" end wrench turn the elastic stop nuts onto the studs until
they are just tight against the rail, then back off ¼ turn so the weighrail is
just free to move. (This adjustment is critical to proper scale
performance.) The weighrail now floats between the dead rails and
prevents binding and torque on the load cells when the load is applied.
Since the entire scale becomes an integral part of the overall
monorail system, normal deflection of the system will not affect scale
accuracy - that is, the scale moves with adjacent rail, not in opposition to
it, as there is no differential movement. However, the design of a safe,
stable, supporting structure adjacent to the scale is essential and is the
responsibility of the customer.
